The “over versus under” toilet paper argument has been waged in bathrooms everywhere since it was first invented.

Plenty of space online in the form of polls and listicles has been dedicated to the proper way to orient our toilet paper.

The subject even has its own section on Wikipedia filled with arguments for “over” (reduces the risk of transferring germs, easier to find the end, looks better) versus “under” (tidier appearance, harder for a pet to unravel the roll).

And now, thanks to a patent for perforated toilet paper from 1891, we officially have our answer.

“Since the advent of rolls of paper…many devices designed to prevent waste have been patented; but all effort in this direction has been apart from the roll of paper-namely, in the construction of holders for the rolls provided with means to prevent free unwinding of the roll and cause the sheets to separate singly at their connecting points,” Wheeler wrote in his patent.
